Michael from ProdMod designed a high powered version of his photo light using a Luxeon LED with heatsink -
The following project is a neat way to make your own high powered video light to attach to your digital camera or camcorder. I called it the NightVlogger 160 after I read the term on this article of someone willing to use this type of light to allow him to take paparrazi style video at night. At 160 lumen it is very bright and fits in a slim AAA battery holder using only 3 batteries.
He’s also considering releasing a kit for the device. Head over to the site for more info – ProdMod Night Vlogger 160
